Re: Volume bars are plotted right half when weekends are exc

In addition, it must be worth noting down is that candlesticks are being plotted as expected (2 halves) even though weekends are excluded. CandlestickRenderer provided by the framework is being utilized for candlestick charts.

When weekends are excluded using monday through friday segmented time line for a combined domain xy plot, the width of the volume bars are reduced to half and only right half of the bars are plotted. This is because mid night time is the reference time used. Since weekends are excluded, bar plot whi...

Issue with using monday through friday SegmentedTimeline.

I am using a segmented timeline created by SegmentedTimeline.newMondayThroughFridayTimeline() for my date axis. This is hiding Saturday/Sunday from date axis as expected. However, whenever there is data for saturday/sunday time frame, the data is being appended to Monday's data which is incorrect. F...

Re: Date is merged incorrectly when using SegmentedTimeline

This whole question actually boils down to "Should the charts be showing date tick label for Saturdays when they are excluded using SegmentedTimeLine?"
